ALARM-BELL FOR BICYCLES.

SPECIFICATION forming part of Letters Patent No. 285,933, dated October 2, 1883. Application filed March 2!), 1883. (No model.)

To all whom, it may concern:

Be it known that I, HAROLD SEnnnLL, of Ilainiield, in the county of Union and State of New Jersey, have invented an Improvement in Alarm-Bells for Bicycles, and the following is declared to be a description of the same.

Alarnrbells for bi cycles have been 001 structed for use upon both the handle-bar of the machine and the upright arm of the brake. Most of these bells are adapted to give a single stroke. Some will give several. vibrations of the hannner for each pull of the lever, and some are operated by a roller running upon the rubber tire of the large wheel of the machine, and when brought into action give out a c011- tinuous alarm until released.

The object of my invention is to provide an alarm-bell for bicycles that is adapted to le actuated at either thehaudlebar or the brakearm of the machine, and that will give an alarm of greater or less duration at the discretion of the rider, or which may be continued in operation until run down, and which may be wound up by the rider.

My invention consists in an alarm-bell for bicycles in which a spring is employed, and mechanism for winding said spring, ahammer and mechanism for operating the same, and mechanism for holding the hammer in a state of rest when the bell is not in use.

In the drawings, Figure l is an elevation of the base-plate andalarm mechanism and a sec tion of the gong. Fig. 2 is a plan of the same with the gong removed. Fig. 3 is an elevation of the bell complete as adapted to the brake-arm. Fig. 4 is a plan of the windinglmtton, and Fig. 5 is a perspective view of part of a machine with a bell in both positions.

The base-plate a, Fig. 1, is made with ajaw, a, for the reception of the handle-bar of the bicycle, and it is provided witha screw-nut, 05-, to press on said bar and clamp the base plate a and alarm-bell and mechanism in place. The base-plate a, Fig. 3, is made with projecting lugs Z) and a yoke or strap piece, c, for passing around the brake-arm of the bicycle; and screws (1 d are provided for clamping the yoke to the base-plate and holding the plate and bell upon the machine. Into this baseplate a, I secure three or more standards, 0,

and I provide a plate, f, with openings, into which the ends of these standards pass and are secured. A section of tubing, g, is upon this plate f, and its upper portion is cut with a niale screw fitting a female thread in the opening in the top of the gong 71 and I provide a nut or ring, a, screwing upon the thread of g, to clamp the gong in'position. There should be a shoulder on the tube 9 for the gong to rest upon.

'The alarm mechanism consists of the spring 7v, toothed wheel Z, ratchet m, pinion or, escapement-wheel 0, anchor 12, and wire and hammer r. The spring It! is upon the arbor k, and said arbor k has a bearing in the base-plate a and a shoulder at the plate fan d it extends up through said plate through the tubing 9, and a thread is cut on the end of sai d arbor for the winding-button .9, employed in winding up the alari'n. Instead of cutting a screw-thread on the arbor k, the end may be square and a key orbutton, s, fitted to it. The whole of this alarm mechanism is contained within the gong and between it and the base-plate, and being so confined is out of sight, is neat and compact, and the bell protects the parts from dust to a large extent. The curved lever t is secured upon the base plate a by a rivet in such a manner that it is held in place, but may be swung upon the rivet, and this lever has a broad end, to be grasped by the fingers, and I provide a spiral spring, a, with one end secured to a standard, 6, and the other end to the end of said lever t, which is turned up at right angles to the main portion. This turned-up end of the levert takes a bearing against the wire of the hammer r, and the force exerted by the spiral spring a retains the alarm, mechanism in a state of rest.

The alarm is operated in the following man= ner upon the bicycle: The spring k is wound up by turning the button .9 either before the rider starts out or while he is riding on the road. If he wishes to give an alarm, he presses against the broad end of the lever t, elongating the spiral spring a and releasing the wire and hammer r and alarm mechanism, and so allowing the alarm to sound. A short alarm, a long alarm, and avariety of combinations of short and long alarms may be sounded according to the length of time the pressure is maintained upon the lever '15, as the moment the r lever t is released the spring returns the lever to its normal position and holds the hammer in a state of rest.

In connection with my alarm a sliding rod and spring secured upon the handlebar of the bicycle may be used, so that said alarm can be operated without-removing the hands from the handlebar of the machine.

I claim as my invention- 1. I11 a bell for bicycles, the combination, with the gong and base-plate, and mechanism for removably attaching said, base-plate to the brake-arm or handle-bar, of striking mechanism within the gong and between it and the base-plate, the button 8 upon the arbor of the main spring and outside the gong for winding up the alarm-spring, and the hand-lever or stop't and spring uior holding the hammerwire 1* and stopping the alarm, substantially as set forth. r

2. A gong-bell for bicycles, its spring and striking mechanism, in combination with the base-plate and mechanism for removably at taching the same to the brake-arm or handlebar, substantially as specified.

Signed by me this 27th day of March, A. D. 1883.
